Audit in Oracle

Hello, everybody!
I have a problem in auditing some user actions in Oracle.
For example, how could I audit using of GRANT ANY PRIVILEGE privilege?
I asked it for auditing:
AUDIT GRANT ANY PRIVILEGE BY ACCESS
The following record has been appeared in the DBA_PRIV_AUDIT_OPTS view.
But when I actually use this privilege nothing is audited. And I'm sure
that I really use it because when I revoke this privilege from my user
I can't grant any privilege.

So, does anybody know what did I do wrong?
